The Effect of Different Solid Dispersive on the Growth and the Survival Rate of Pantau Janggut (Esamus Metallicus) Seed In Cage Culture

Abstract

The study was conducted from July to September 2012, which was held in the experimental ponds of Fisheries and Marine Sciences Faculty of Riau University Pekanbaru . The purpose of this study was to determine the appropriate solid dispersive in the maintaining of Pantau Janggut fish (EsamusMetallicus) in the cage culture. The fish used in this study was the Pantau Janggut seed with 4-5 cm in length. Cage culture, with size of (1x 1 x 1) m3 consists of 12 units and the feed given was the shrimp pellets. The method used in this study was an experimental method using a completely randomized design (CRD) with four treatments and three replications. The treatment given P1 = solid dispersive of 25 cages / P2 = solid dispersive of 30 cages P3 = solid dispersive of 35 cages and P4 = 40 solid dispersive cages. The best treatment was P1 with absolute growth weight of 5.14 g, total of absolute growth length of 5.22 cm, daily growth rate of 0.76% and survival of 97.92%. Water quality parameters during the study was temperature 29-320C, pH 6-7 and dissolved oxygen (DO) from 2.53 to 2.95 mg / l.
